MTK Logger (iBlue 747,Qstarz BT-1000,...) download (mtk)

This format is the serial download protocol for the MTK chips.
Mediatek's MT3301/3179 (MTKv1) and MT3318 (MTKv2) chips are used
in a large number of products sold under different names.

Many GPS products, especially of the data logger variety, expose
the Mediatek protocol to the user via USB. Some modify Mediatek's
protocol in minor ways, but the core protocol is very commonly
seen in loggers.

The following products are known or are expected to work with this module.
As the products are typically very low cost, they tend to have a short
product life cycle and are often imported to different areas under
different names. Keeping
track of the list is difficult. Often the "same" GPS is sold in different
plastic or with different Windows software or different options such as
compass or motion sensors or charging cables with different model numbers.
If you can confirm success with others, please share with us.

Downloaded data will be stored in data.bin file in the current
directory together with the choosen output format. This is a rather
uncommon feature in GPSBabel's formats and is likely to change in future
versions.
